IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No. 125,320, dated April 2, 1872.

To all whom it may concern:

Be it known that I, GIDEON F. Moonn, of Wilmington, in the county of Clinton and State of Ohio, have invented an Improved Sash-Fastener; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing forming part of this specification, in which- Fignre l is a vertical section of my improved fastener, showing its application to a windowsash. Fig. 2 is a perspective view of the fastener detached from the sash.

Similar letters of reference in the accompanyin g drawing denote the same parts.

My invention has for its object to provide an improved fastener for window-sashes of that class which automatically lock the sash in place when closed, and furnish a handle by which to raise the same, the operation of raising at the same time unlocking the sash from the window-sill. To this end the invention consists of a catch or lever pivoted near its center in a metallic case and forced outward by a spring, so that a hook on its lower end projects through an orifice in the front of the case, and operated by a secondary lever, which is pivoted in the case above the spring-catch, and projects outward through the front of the case, the projecting end constituting a handle for raising the window-sash, while the inner end, bearing against the upper end of the springcatch, disengages the same from the window ledge or casing when an upward force is exerted. The details of construction and method of operation will be more fully described hereinafter.

A represents a metallic plate, on the back of which is cast a vertical rectangular case, B, the ends of which are open. The plate A is provided with screw-holes c and with orifices cl 6 at the top and bottom, which open into the case B. D represents a catch or lever, which is pivoted nearly in the center of the case B, and extends downward to the bottom of the same, where it is provided with a hook, d, which projects through the orifice e of plate A. The catch D is held in the position shown by a flat spring, E, which is at tached to the same near its upper end, and bears against the back of the case B. H represents a lever, which is pivoted in the case B above the catch D, and whose outer end projects through the orifice d of plate A, where it is curved slightly into a handle, I. The rear end of lever H projects downward, forming, as it were, a bell-crank lever, the lower side of which is curved, as shown in Fig. 1, and bears upon the upper end of the catch D, which is also rounded.

The operation of my invention will be readily understood. The fastening is attached to the lower cross-bar of the sash, the hook of the catch D, when in its natural position, projecting through the front of the plate, and engaging with a mortise in the window-ledge, as shown in Fig. 1. By lifting the handle I slightly, the rear portion of the lever H is caused to engage with the upper end'of the catch D and turn the same on its pivot sufficiently far to disengage the hook cl from the mortise, thereby unlocking the sash, which can then be raised as desired by the handle I, the same acting to unlock the sash and as a handle by which to raise it, both operationsviz., the unlocking and raising-being per? formed simultaneously.

The construction of the fastener is extremely cheap, simple, and strong, and it can be readily attached to an ordinary window-sash by cutting a mortise for the case B and fastening the same by screws through the plate A. This arrangement is adapted to car or' house windows, obviating in the former case the use of a separate handle for raising the window. It should be understood, however, that by the use of this device the sash is only locked when closed. It will be seen that the sash locks automatically when it is closed, the hook at, which has a slanting outer surface, yielding to the window-sill when it comes in contact therewith, and springing into the mortise. The window-sill 'and mortise are protected from injury from the hook when the sash descends by a metal plate, 45, which has an orifice corresponding in size to said mortise, and is attached to the sill over the same, as shown in Fig. 1.

By inverting the above-described fastening it can be used to lock the upper sash of a window from the top and prevent the same from being lowered.
